[CodeQuality] Respect typeGuardedClasses and skip closure-only returns in ResponseReturnTypeControllerActionRector

[TomasVotruba]

Two fixes for ResponseReturnTypeControllerActionRector.

1. Respect typeGuardedClasses

Follow-up to rectorphp/rector-src#8135. The rule wrote return types even into classes the user guarded via withTypeGuardedClasses(), which is a breaking change for their child classes. Now it bails out through ParentClassMethodTypeOverrideGuard::isTypeGuardedClass().

With ->withTypeGuardedClasses([AbstractCustomController::class]):

-class SomeController extends AbstractCustomController
+class SomeController extends AbstractCustomController // non-final = guarded, left alone
 {
     #[Route]
     public function detail()
     {
         return $this->render('some_template');
     }
 }

Final classes cannot be extended, so they are still refactored:

 final class SomeController extends AbstractCustomController
 {
     #[Route]
-    public function detail()
+    public function detail(): \Symfony\Component\HttpFoundation\Response
     {
         return $this->render('some_template');
     }
 }

Controllers outside the guarded tree are untouched by the option:

 class SomeController extends AbstractController
 {
     #[Route]
-    public function detail()
+    public function detail(): \Symfony\Component\HttpFoundation\Response
     {
         return $this->render('some_template');
     }
 }

2. Skip methods whose only return lives in a closure

hasReturn() used the unscoped hasInstancesOf(), so a closure body counted as the method's return. isResponseReturnMethod() then saw zero scoped returns and vacuously returned true, producing a bogus type on a method that returns nothing:

 final class SomeController extends AbstractController
 {
     #[Route]
-    public function detail()
+    public function detail(): \Symfony\Component\HttpFoundation\RedirectResponse
     {
         $callback = function () {
             return 'hey';
         };

         $callback();
     }
 }

Switched to hasInstancesOfInFunctionLikeScoped().
